Cunnilingus And Cum

I was licking and tonguing my wifes pussy, noticing how creamy and beautifully tasting it was, when she told me Ben our neighbour, had just fucked her.
I raised my head, but she pushed my face back into her soaking wet c**t, telling me to make her orgasm.
I was torn between being angry at what she'd just told me, and wanting, needing to pleasure her vagina and clit.
So knowing I was actually enjoying tasting his cum from her freshly fucked pussy, I delved my tongue deep inside her and felt his cum flowing into my mouth.
And I've now been doing precisely that for nine wonderful months.
They fuck two or three times a week, and each and every time afterwards I give my wife an extended session of cunnilingus.
I have no desire to taste Ben's cum directly from source. But then I've never sucked cock.
Maybe.
